STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 403,787, dated May 21,1889.

Application filed April 12, 1888. Serial No. 270,445. (No model.)

To a ZZ whom it may concern:

Be it known that I, Osonn F. STEDMAN, of Ravenna, in the county ofPortage and State of Ohio, have invented certain new and usefulImprovements in Stem Vinding and Setting Vatches; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in stem win ding and settingwatches; and it consists in the combination of the endwise-movingwinding-stem provided with a spring and a stop-flange with a sleevewhich is placed in and secured to the pendant, and which is enlarged atits lower portion, so that the spring will engage with the upper end andhold the stem in position when forced inward for the purpose ofoperating the winding mechanism, all of which will be more fullydescribed hercinafter.

The object of my inventionis to use in connection with an endwise movingwindingstem a single lever which will both move the yoke into positionfor setting the hands and lock it in that position, and to form upon orattach to the endwise-moving stem a spring which,by frictional contactwith the sleeve in the pendant, will hold the winding-stem in positionwhen forced inward.

Figures 1 and 2 are side elevations of a watch embodying my invention,the parts being shown in different positions. Figs. 3 and at are similarviews taken from the opposite side of the pillar-plate, and also showthe partsin different positions.

A represents the pillar-plate, to one edge of which is secured the frameB, in which the winding-pinion C is placed in the usual manner, andthrough which the inner angular end of the winding-stem D moves back andforth. Pivoted upon this pillar-plate is the lever E, with the shorterarm of which the inner end of the winding-ste1n D comes in contact whenthe stem is forced inward for the purpose of winding the watch, andwhich lever E has a projection,F, formed at or near the end of itslonger arm. This projection F passes through the slot G, formed in thepillar-plate, and has secured to it upon the opposite side of thepillar-plate from the lever the spring II, which always returns thelever to position whenleft free to move. Vhile the winding stem isforced inward this lever E has its projection F forced back out ofcontact with the yoke I but when the winding-stem is drawn outward forthe purpose of setting the watch the spring H forces the lGVOl' E topartiallyturn upon its pivot and bring the projection F in contact withthe end of the yoke I to force it in position for setting the hands andlooking it. This yoke I, carrying the intermediate winding and settingwheels in the usual manner, is provided with a notch or recess, J nearone end, and in which the projection F on the lever E is made to catchwhen the yoke is to be locked in position for setting the hands. hen thelever E is moved into that position where the projection F is not incontact with the yoke, then the spring L, which is weaker than the oneH, at once moves the yoke, so as to bring the winding-wheels intoposition for winding the watch. hen the projection F is forced back outof the notch J, it is also forced back out of contact with the end ofthe yoke, so as to allow the yoke to have a free vibratory motion whilethe watch is being wound. The spring II, being more powerful than theone L, overcomes its action, and as soon as the winding-stem is drawnoutward the spring II instantly forces the yoke into position forsetting the hands. lVhen the winding-stem is forced inward, the actionof the spring II is overcome, and then the spring L is left free to actupon the yoke to force it into position for winding the watch.

Inside of the pendant N is rigidly secured the sleeve 0, which is madelarger at its inner than its outer end, and through which sleeve passesthe winding-stem D. Upon this winding-stem is formed the stop orfiangeP, which, when the winding-stein is d awn upward by its crown Q, strikesagainst the inner end of the sleeve and prevents any further movement inthat direction. Secured to or formed as a part of this stem D are one ormore springs, R, which project outward either in a line with the stem orat any suitable angle thereto. Vhen the stem is pushed inward and theopening through the sleeve.

outer end of the spring strikes against the inclined shoulder S insideof the sleeve, the spring is compressed against the side of the stem andmoves endWise into the smaller This spring by its frictional contactwith the sleeve holds the stem in position, so that it will not beaccidentally moved while the hands are being set. These springs exertenough resistance against the outward movement of the stem to prevent itfrom being moved except when a pullis exerted upon it, and when thispull is exerted the spring or springs are forced by the inclinedshoulder S toward the side of the stem, so that they can enter the upperportion of the sleeve.

The spring R is here shown for the purpose of locking the winding-stemin position; butI do not limit myself to this particular construction,because any other construction which may be preferred for locking thewinding-stein may be used.

Having thus described my invention, I claim The combination of theendwise-moving winding-stern provided with a stop, P, and a
